*"orirrnn 311A? STACKER.

Application filed October 12, 1915.

To all whom it may concern:

Be it known that I, FRANK J. MAG- DONALD, a citizen of the UnitedStates, residing at VVarnerville, in the county of Schoharie, State ofNew York, have invented certain new and useful Improvements in Stackers;and 1 do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in stacker-s and particularly topneumatic stackers.

The principal object of the invention is to provide a device in whichthe grain usually lost as the straw is blown up through the tube, may besaved.

Other objects reside in the peculiar construction and arrangement of thevarious parts which combine to perform the functions desired.

In the drawing: Figure 1 is a side elevation of my improved stackingdevice, Fig. 2 is a top plan view, Fig. 3 is a longitudinal section onthe line 3-3 of Fig. 2, Fig. 4 is a transverse section on the line 44 ofFig. 2, Fig. 5 is a horizontal section on the line 5-5 of Fig. 1, andFig. 6 is a longitudinal section on the line 6-6 of Fig. 2.

Referring particularly to the accompanying drawing, 10 represents apulley or belt wheel mounted on the cylinder shaft 11 of a threshingmachine. On the said machine is mounted a frame 12 which supports a fancasing 13 having an opening 14 in one side to receive the straw from thehopper carried by the said frame 12. This hopper inclines longitudinallydownwardly and inwardly and inwardly transversely, the lowest pointbeing formed with an opening 16 over which is disposed a grating 17.Mounted in the casing 13 is the fan 18 which has on the outer end of itsshaft a pulley 19 which is driven from the cylinder shaft 11 by a belt20. Connected to the upper side of the casing 13 is the stacker tube 21,

flopiea of this patent may be obtained for Specification of LettersPatent.

Serial No. 55,463.

the same being mounted ona turn table 22 rotatable by means of the wormor screw pinions 23 and 24. The stacker tube is provided with anadjustable guard grating 25 at its outer end and with winding drums 26and 27, and the complementary cables 28 and 29 for raising and loweringthe tube and for extending or retracting the same. In the opposite lowerside of the casing 13 there are formed a plurality of openings 30.Extending from these openings to a point beneath the opening 16 is anair conducting pipe 31 which conveys air from the casing 13 anddischarges the same upwardly through the grating 17 so as to separateany grain which might be in the straw and permit the same to fallthrough the grating. Disposed below the grating and the adjacent end ofthe pipe 31 is a chute 32 beneath which a suitable receptacle can beplaced to catch the grain as it falls through the grating.

What is claimed is:

A grain saving device for a stacker comprising a fan casing having anopening in one side, one edge of the casing having aplurality of airoutlet openings, a hopper mounted at one side of the casing in positionto discharge material through the opening, the bottom of the hopperhaving an outlet opening and a spout therebelow, said spout incliningdownwardly away from the casing, a grating over the opening in thehopper and an air conducting pipe having one end secured to the casingand covering the said plurality of openings and the other end having anozzle arranged beneath the grating in position to discharge a blast ofair upwardly through the grating; and inwardly toward the straw openingof the fan casing.

In testimony whereof, I affix my signature, in the presence of twowitnesses.
